Please refer to FIG. 16. FIG. 16 is a perspective diagram of the safetyseat 3 with a supporting cushion apparatus 1 according to an embodimentof the present application. As shown in FIG. 16, the present applicationfurther discloses that a safety seat 3 includes a main body 31 and thesupporting cushion apparatus 1 disposed on the main body 31. Thesupporting cushion apparatus 1 can be a headrest for supporting theinfant's head in the safety seat 3. The supporting cushion apparatus 1includes the fireproof buffering structure disclosed by the presentapplication so as to provide protection for the infant's head.

Please refer to FIG. 17 and FIG. 18. FIG. 17 is a perspective diagram ofthe supporting cushion apparatus 1 according to the embodiment of thepresent application. FIG. 18 is a diagram of the fireproof bufferingstructure 45 partially accommodated in a covering pocket 113 accordingto an embodiment of the present application. The supporting apparatus 1includes a covering member 11 and the fireproof buffering structure 45accommodated inside the covering member 11. The fireproof bufferingstructure 45 can be a structure of the abovementioned fifth embodiment,which includes the buffering plate 451, and the fireproof plate 452 andthe first auxiliary fireproof plate 453 respectively attached to a frontsurface of the buffering plate 451 and a rear surface of the bufferingplate 451. The covering member 11 includes a head supporting portion 111and two flanking portions 112 connected with two sides of the headsupporting portion 111. A child in a car ride can rest his or her headon the head supporting portion 111. The fireproof buffering structure 45can be accommodated in each of the two flanking portions 112 which arelocated on two sides of the child's head for providing protection.Specifically, the covering pocket 113 with an opening can be disposed onat least one of the two flanking portions 112 and the head supportingportion 111, and the fireproof buffering structure 45 can be put intothe covering pocket 113 through the opening. A shape of the fireproofbuffering structure 45 can correspond to shapes of the flanking portion112 and the covering pocket 113, and a size of the fireproof bufferingstructure 45 can be only slightly smaller than the covering pocket 113so that the fireproof buffering structure 45 can be properly restrainedin the flanking portion 112 after being enclosed into the coveringpocket 113. The fireproof buffering structure 45 can also beaccommodated in the head supporting portion 111. For example, in anotherembodiment of the present application, the fireproof bufferingstructures 45 are accommodated in the head supporting portion 111 andthe flanking portions 112 of the covering member 11. In anotherembodiment of the present application, the fireproof buffering structure45 is accommodated only in the head supporting portion 111 but not inthe flanking portions 112, and the description of the exemplaryembodiments are intended to be illustrative and not to limit the scopeof the invention.

Since the fireproof plate 452 made of PE is harder than the bufferingplate 451 and is disposed on a surface of the fireproof bufferingstructure 45 closer to an inner space surrounded by the covering member11, the infant with his or her head rested in the inner space and on thefireproof plate 452 might feel uncomfortable. Therefore, a soft fillercan be disposed on the fireproof plate 452 accommodated in the flankingportion 112. A side compartment can be disposed outside the coveringpocket 113 accommodated in the flanking portion 112 or in the headsupporting portion 111, and the soft filler can fill the sidecompartment. In other embodiments, the soft filler can directly fill thecovering pocket 113 for covering the fireproof plate 452 or can bedisposed on the fireproof plate 452 accommodated in the covering pocket113 or the head supporting portion 111, and the description of theexemplary embodiments are not intended to limit the scope of theinvention but to be illustrative about that the soft filler is requiredto be positioned on an outer surface of the fireproof plate 452. Thesoft filler can be foam made of materials, such as PU, EPP, EPS, or EPE,or can be made of a material that improves comfortableness, such ascotton. It is noticed that the fireproof buffering structureaccommodated in the supporting cushion apparatus 1 can be formed inother configurations else the fireproof buffering structures of thefirst embodiment to the tenth embodiment besides the abovementionedfireproof buffering structure 45.

In contrast to conventional buffering structures, the fireproofbuffering structure of the present application includes the bufferingplate and the fireproof plate combined with each other. The bufferingplate has good impact absorbing capacity for providing a soft andcomfortable seating environment and buffering and protection effectsduring a crash accident. Besides, the attached fireproof plate canreduce the combustion rate of the integral structure when catching fire.Therefore, the fireproof buffering structure, which can be disposed inthe safety seats achieves the inventive purposes of safety and comfort.
